What is Katana
Inventory management for multi-channel businesses
Katana is a cloud-based inventory management platform built for product businesses that sell across multiple channels. It centralises inventory, orders, and fulfilment in a single real-time system, replacing the spreadsheets and disconnected tools that hold growing businesses back.
Simplify your inventory and scale your business
Traditional inventory software was built for enterprises with big IT budgets: six-figure ERPs that take months to implement and full-time specialists to run. Katana was designed for the opposite: lean, growing businesses who need real operational control without the cost or complexity.
When you connect Katana to your sales channels, it automatically pulls in orders, adjusts stock levels in real time, and gives your team a single source of truth across every location. No manual reconciliation. No phantom stock. No overselling products you don’t have.
What Katana is not
Katana is not an ERP. It’s not built for enterprises with 500-person IT teams or six-month implementation timelines. It’s not a basic stock counter that breaks the moment you add a second sales channel.
It occupies the sweet spot: inventory and operations management for multi-channel product businesses that have outgrown spreadsheets but don’t want to use outdated traditional ERPs.
Who it’s for
Built for multi-channel merchants
Katana’s free plan is designed for growing product businesses, typically $1M–$10M in revenue, selling across two or more channels with a lean team. If any of these sounds like you, you’re in the right place.
If I didn’t have Katana, I would be drowning in spreadsheets, which would all break at some point.

How the Free Plan works
Get up and running in days, not months
The free plan is a permanent free tier, not a trial that cuts you off after 14 days. No credit card. No expiry date. Here’s exactly what you get.
Katana’s free plan includes up to 30 SKUs, 3 inventory locations, unlimited users, all integrations, API access, and all core platform features, with no time limit and no credit card required. A 15-day grace period lets you explore the full platform with your entire catalog before the SKU limit applies.
What’s not included in the free plan
The free plan has one meaningful constraint: 30 active SKUs after the grace period. If your catalog is larger, the Core plan starts at $299/month and removes the SKU cap entirely, adding unlimited SKUs and 24/7 support.
- Up to 30 SKUs. Enough to cover your core product range. Hit that ceiling? Upgrade when you’re ready.
- 3 inventory locations. Track stock across your warehouse, a 3PL, and a retail location simultaneously.
- Unlimited users. Your whole team on the same platform, for free. No per-seat fees eating into your margin.
- All core features: real-time inventory tracking, purchase orders, sales orders, bill of materials, and fulfilment workflows. Not a stripped-down demo.
- All integrations included. Connect Shopify, Amazon, QuickBooks, Xero, and more from day one. No integration is gated behind a paid plan.
- API access. Build custom workflows or connect tools that aren’t in the native integration library.
- 15-day full-access grace period. Explore Katana with your complete SKU catalog when you sign up. The 30-SKU limit only kicks in after the grace period ends.

Katana features
Everything you need to run inventory properly
The free plan is the full Katana platform, not a demo. Katana supports your workflows, regardless of industry, with the features and seamless integrations needed to do business your way.

Optimize your inventory
What inventory looks like before and after Katana
Most growing product businesses hit the same wall: Shopify syncs to one spreadsheet, Amazon pulls from another, the 3PL emails a report once a week, and wholesale orders live in a third place entirely. It works until it doesn’t.
Before Katana
- Multiple spreadsheets. One per channel, reconciled by hand.
- Oversells. Shopify and Amazon don’t share stock in real time.
- Stockout surprises. You find out when a customer complains.
- No margin visibility. 3PL fees, returns, and freight not tied to SKUs.
- Fulfilment delays. Routing orders manually across warehouses.
- Forecasting by gut. “Last year we sold about this many.”
After Katana
- One source of truth. All channels and locations in a single dashboard.
- Automatic stock sync. Sell on Shopify and every channel updates instantly.
- Reorder alerts. Katana flags low stock before you run out.
- Real cost tracking. Know which SKUs and channels are actually profitable.
- Smart fulfilment routing. Orders go to the right location automatically.
- Data-driven forecasting. Plan on real velocity, seasonality, and lead times.

Frequently asked questions
Yes. Katana’s free plan is a permanent free tier, not a time-limited trial. You get up to 30 SKUs, 3 inventory locations, unlimited users, all integrations, and access to all core features, with no credit card required and no expiry date. When you first sign up, a 15-day grace period gives you full access to the platform with your entire SKU catalog before the 30-SKU limit applies.
Katana is used by product businesses to manage inventory, orders, and fulfilment across multiple sales channels and locations. Common use cases include: syncing stock automatically between Shopify and Amazon; tracking components and bills of materials for assembled or manufactured products; managing purchase orders with suppliers; routing fulfilment across warehouses and 3PLs; and replacing spreadsheets as a business scales past the point where manual tracking is sustainable.
A SKU (Stock Keeping Unit) is each unique product variant you track in Katana. For example, a t-shirt available in 3 sizes and 2 colours = 6 SKUs. If your business has 30 or fewer active SKUs, the free plan covers you indefinitely. If your catalog is larger, the 15-day grace period lets you evaluate Katana with your full product range before deciding whether to upgrade to the Core plan (from $299/month) for unlimited SKUs.
All integrations are included in the free plan: Shopify, Amazon FBA, BigCommerce, WooCommerce, QuickBooks Online, Xero, HubSpot, and more. API access is also included. The only thing that changes on the Core plan is the SKU cap is removed and 24/7 support is added.
Spreadsheets are static: they show a snapshot of what was true when someone last updated them. Katana is live. Inventory levels update automatically as orders come in, stock is received, and fulfilments ship, across every connected channel at once. Katana also handles purchase orders, bills of materials, multi-location allocation, and demand forecasting in ways spreadsheets cannot. Most businesses switch when spreadsheet errors start costing them in oversells, stockouts, or hours of manual reconciliation every week.
Most businesses are up and running in under 30 days. Traditional ERPs typically require 6 to 12 months to implement. The free plan lets you start in minutes: connect Shopify, import your products, and your live inventory syncs automatically. Katana provides onboarding resources, and paid plans include 24/7 support to accelerate the process.
Yes. You can upgrade to the Core plan at any time. All your data and settings carry over. The Core plan starts at $299/month, removes the SKU cap, unlocks all integrations, and includes 24/7 support. Usage-based pricing scales with your order volume, and annual billing is available for predictable, fixed pricing. See pricing details →
Yes. Katana was designed for small and mid-sized product businesses, typically $1M–$10M in revenue with lean teams of 3–10 people. It’s simple enough to run without an IT department, and built to scale as the business grows. The free plan gives small businesses access to real inventory management without the upfront cost of enterprise software.
